SPECIFICATION forming part of Letters Patent N 0. 652,853, dated July 3,1900.

Application filed February 15, 190d. Serial No. 5,377. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM F. MAGILL, a

citizen of the United States, residing at Du-' fur, in the county of\Vasco and State of Oregon, have invented a new and useful Cultivator,of which the following is a specifica tion.

My invention is an improved cultivatordesigned especially for killingweeds on and cultivating fallow lands; and itcons'ists in a cutter-bladeadapted to be trailed or drawn from its front end, having a cutting edgeon its lower side for entering the earth and lat-- erally-disposedcutter-wings on the sides of said cutter-blade, said wings being adaptedto operate under the surface of the earth.

My invention further consists in. the peculiar construction andcombination of devices hereinafter fully set forth, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of acultivator constructed in accordancewith my improvements. Fig. 2 is adetail perspective view of one of my improved cultivator devices. Fig. 3is a detail sectional view of the same on. the line 3 3 of Fig. 1looking rearwardly. Fig. 4 is a diagram illustrating the relativearrangement of one of my cultivating devices and means for raising andlowering the same.

The draft-frame 1, which, as here shown, is provided withsupporting-wheels 2, a tongue 3 for the attachment of draft-animals, anda seat 4 for the driver, may be of any suitable preferred construction.

My invention primarily consists in the peculiarly-constructedcultivating device,which may be described as follows: A cutter-blade 5,which, as here shown, is substantially in' the form of a runner, butwhich may be of other suitable form, if preferred, has the lower cuttingedge 6, which is adapted to enter the earth. The cutter-blade may be ofany preferred length and is adapted to be drawn along in a straight lineby suitable connecting devices which attach to it the draft-frame. On.the sides of the cutterblade are arranged laterally-extendingcutter-wings 7, which, as shown in the drawings, are preferably adaptedtooperate horizontally in and below the surface of the earth. Saidcutter-wings have cutting edges, as at 8, at their front sides and ablemanner, as at 10.

are upturned at their inner ends, as at 9, which upturned portions 9bear against opposite sides of the cutter-bladeo and are socured theretoby bolts or in any other suit- The said wings are preferably separablefrom said cutter-blade for the purposes of sharpening and renewal whennecessary or desirable. The cutter- Wings are disposed one in advance ofthe other, as shown, and are obliquely disposed with relation to thecutter-blades and preferablyat right angles toeach other.

The cultivating device above described when in use operates as follows:The cutterblade enters the ground to any required depth and tends toadvance in a straight line, serving to center and support thecutter-wings and establish a line of draft therefor, the cutter-bladewhen in operation being depressed a sufficient depth in the earth tocause the cutter-wings to operate below the surface of the earth, andthereby effectuallyloosen and cultivate the same and also destroy weedsand other growth.

The oblique arrangement of the cutterwings, hereinbefore described,causes the draft stresses on the oppositely-disposed cutterwin gs tocounteract each other, and thereby promotethe progress of thecutter-blade in a straight line.

As illustrated in Figs. 1 and 3, the front ends of the cutter-blades areconnected pivotally to the draft-frame by means of drawbars 11, orchains or othersuitable means may be employed to connect saidcutterblades to the draft-frame. I have also shown in Figs. 1 and 4 arock-shaft 12, mounted in suitable hearings on the draft-frame, operatedby a hand-lever l3, and having arms 14, which'are connected by rigidlinks 15 to a cross-bar 16, attached to and connecting the cutter-bladesin series and in parallel relation to each other. This construction andcombination of devices provides a means for raising and lowering thecultivating devices and for adjusting the latter so as to cause them tooperate at any required depth; but it will be readily understood thatother suit able means may be employed for raising, lowering, andadjusting my improved cultivat ing devices, and hence I do not desire tolimit myself to the use of any particular form of means for suchpurposes in combination with my said improved cultivating devices.

As shown in Fig. 1, the cultivating devices are arranged in series, withthe cutter-blades parallel in relation to each other and with thecutter-wings on the opposing sides of said cutter-blades overlappingeach other, this arrangement insuring the thorough cultivation of theearth between the cutter-blades.

Having thus described my invention, I claim- 1. In a cultivator, thecombination with a draft-frame, of a cutter-blade (one or more)connected at its front end to the draft-frame whereby the cutter-bladeis adapted to be drawn or trailed, said cutter-blade having a cuttingedge on its lower side extending throughout the length thereof, andprovided with laterally-extending cutter-wings on its sides, adapted tooperate under the surface of the soil and means to raise and lower saidcutter-blade, substantially as described.

2. In a cultivator, the combination with a draft-frame, of acutter-blade (one or more) connected at its front end to thedraft-frame, whereby the cutter-blade is adapted to be drawn or trailed,said cutter-blade having a cutting edge on its lower side extendingthroughout the length thereof, and provided with laterally-extendingcutter-wings on its sides, adapted to operate under the surface of thesoil and a lever mounted on the draft frame and connections between saidlever and said cutter-blade, to raise and lower the latter and hold thesame when depressed, substantially as described.

3. In a cultivator, the combination with a draft-frame, of a series oftrailing cultivatorblades connected at their front ends to thedraft-frame and having cutting edges on their lower sides andlaterally-projecting cutterwings on their sides, adapted to operateunder the surface of the soil, a bar bearing on and connecting saidseries of trailing cultivatorblades,a rock-shaft carried by thedraft-frame and having rock-arms, a lever to turn said rock-shaft, andlinks connecting said rockshatt to said bar, substantially as described.

4. A cultivator cutter blade or runner adapted to be trailed or drawnfrom its front end and having the cutting edge on its lower sideextending throughout its length, and the laterally-extendingcutter-Wings on its sides, for the purpose set forth substantially asdescribed.

5. In a cultivator, a series of cutter-blades having cutting edges ontheir lower sides adapted for entering the earth, and laterallydisposedcutter-wings on the sides of said cutter-blades, adapted to operateunder the surface of the earth, the wings on the proximate sides of saidseries of cutter-blades being disposed in overlapping relation to eachother, for the purpose set forth, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses:
